What is PGT-A?
Preimplantation Genetic Testing for Aneuploidy (PGT-A) is a genetic test that can be performed on embryos to identify any with abnormal chromosome numbers (aneuploidy). This test is performed on a developing embryo, prior to the embryo transfer step in IVF treatment, with the goal of improving the likelihood of implantation. To learn more about how PGT-A helps improve implantation rates, visit our recent blog post and the video below.
How does PGT-A Screening work?
Through a quick, non-invasive biopsy of trophectoderm (TE) cells of a day 5 blastocyst, we are able to ensure the exact number and DNA content of each chromosome within each embryo sample. Only TE cells are needed for the biopsy. They are the outer cells that grow to be the placenta. The inner mass cells that grow to become the fetus are NOT biopsied for PGT-A.
Is PGT-A right for me?PGT-A has been shown to improve implantation rates for individuals of any age, however it is typically most cost-effective for those who:
- Are over 35 years of age
- Have experienced 2+ unsuccessful IVF cycles or pregnancy losses
- Have a known history of chromosomal abnormalities
- Have known male-factor infertility (low quantity or quality of sperm)
